Designer Anthony Marfione
Microtech Knives is an American brand with more than thirty years of history producing top-tier automatic knives. Its hallmark features include:
Each piece is manufactured and assembled in the USA under the leadership of Anthony Marfione.
The Dirac Delta® is a modern interpretation of the tactical OTF knife with an emphasis on ergonomics and speed. The side, recessed slider allows for more natural thumb support and more comfortable handling compared to traditional top sliders.
The model operates in D/A (Double Action) mode – the blade deploys and retracts with a single thumb movement. The mechanism is extremely fast, yet it requires controlled pressure to overcome the spring resistance, which contributes to safety.
For sharpening, we recommend the Spyderco Tri‑Angle Sharpmaker Complete Sharpening System 204MF – ideal for plain edges as well. 🛒 Available on our Moskito.cz website
